After interrogation, the masked man's name was Luo Ying, a small stone mining foreman on the outskirts of Luzhou City. Luo Ying refused to admit that he had bought arsenic in Zhu Bao's pharmacy under the pseudonym Lu Si, and his explanation for entering the pharmacy at night to kill Zhu Bao was that Zhu Bao had sold him fake medicine.

After careful identification, Zhu Bao determined that he was the person who went to the pharmacy that night to buy arsenic and said that his name was Lu Si.

Luo Ying still refuses to admit it,

At this time, Li Tao noticed that Luo Ying's short knife was cast with the word "Zhang Ji".

Isn't Zhang Ji Zhang Jin's iron shop signboard, do the two know each other?

Li Tao immediately called Zhang Jin to ask.

Zhang Jin carefully identified the knife and said that the knife was indeed hit by himself, but he couldn't remember who he had hit it for. He didn't know this Luo Ying either. And when Zhang Wei said that Yujuan's death might be related to Luo Ying, he seemed surprised.

"Isn't the murderer Lu Si?" Zhang Jin asked. Li Tao shook his head and said, "Yujuan was poisoned by arsenic, and this Luo Ying pretended to be Lu Si and bought arsenic in Zhu Bao's pharmacy. Strange things such as the exchange of corpses happened in the middle, so I concluded that the real murderer who killed Yujuan was not Lu Si! ”

"W-How is this possible? I saw Lu Si kill Yujuan with my own eyes, did Xiao Langjun accept his favors?" Zhang Jin said emotionally.

"Bold!" Zhang Wei'an was furious.

Li Tao waved his hand at Zhang Wei and said to Zhang Jin: "Don't worry, I will definitely investigate this case and give you father and daughter an explanation."

Zhang Jinlao burst into tears: "Please be sure to solve the case as soon as possible, otherwise Yujuan will not be blind to her death."

Li Tao sighed and helped Zhang Jin up.

After Zhang Jin left the county office, Li Tao whispered a few words to Zhang Wei, and Zhang Wei nodded.

In the middle of the night, Luo Ying was lying in the corner of the cell tossing and turning, when the cell door suddenly opened, and the official came in and twisted him.

"Y-What are you going to do?" Luo Ying was very nervous.

The official sneered: "Your Excellency, please!"

The official pulled Luo Ying to the door of the lobby and saw Zhang Wei talking to Zhang Jin in the dim lobby.

"Wait here for a moment." The official whispered to Luo Ying.

Zhang Jin in the lobby said angrily: "Didn't you say that Luo Yingcai may be the real murderer, then quickly behead him to avenge my daughter."

Luo Ying's face changed outside the door.

Zhang Wei said: "He has not pleaded guilty yet, so he cannot be reckless."

"The facts are here, since it was the arsenic he bought, it must be him, please kill him quickly to avenge Yujuan." Zhang Jin said and knelt in front of Zhang Wei suddenly: "I begged my lord." ”

Before Zhang Wei could speak, Luo Ying outside the lobby suddenly shouted: "Zhang Jin of the dog day, you fell into the well, I have to kill you."

The official didn't hold him, he had already run into the lobby, pulled up the kneeling Zhang Jin and scolded: "You killed someone but let me be a scapegoat."

Before he finished speaking, he was surprised to notice that the person in front of him was not Zhang Jin at all, but a person who was very similar to Zhang Jin.

Luo Ying's face immediately turned pale.

Zhang Wei shouted: "Luo Ying, still don't recruit from the truth?"

Luo Ying knew that he had been fooled, and sighed and collapsed in front of Zhang Wei.

From Luo Ying's confession, Li Tao and Zhang Wei learned about the case. A few days ago, Luo Ying transported a batch of high-quality stones to Zhao Manyu, a wealthy merchant in the city, who was preparing to build a garden, but Zhao Manyu refused to pay him. Luo Ying tried his best to get it back, and decided to take revenge in anger. So he found Zhang Jin and asked him to give himself a short knife, wanting to scare and scare Zhao Manyu.

That night, he sneaked into Zhao's mansion and accidentally saw Zhao Manyu's daughter Liniang, so he took her captive to his house, prepared to take her hostage, and threatened Zhao Manyu with money. However, when he looked at the beautiful Liniang, he suddenly had a bad thought and wanted to do ** things, Liniang resisted hard, and Luo Ying strangled her to death. happened to be seen by Zhang Jin, who came to ask for knife money.

Zhang Jin immediately used this matter to extort money from Luo Ying, Luo Ying wanted to kill him, but Zhang Jin said that he had told others about it, and if he was killed, this person would sue Luo Ying to the yamen, and Luo Ying was afraid.

That night, Zhang Jin suddenly found Luo Ying, and the two reached a secret deal. Zhang Jin said that his daughter Yujuan was about to be "killed by Lu Si", and asked him to exchange the bodies of Liniang and Yujuan while he was sending Lu Si to the official mansion. And before that, Zhang Jin also asked Luo Ying to go to the pharmacy in the name of Lu Si to buy half a tael of arsenic for himself. As for the rest, I don't know anything, and Yujuan really didn't kill herself.

After Luo Ying explained this, Zhang Wei was dumbfounded. Li Tao sighed and said, "Zhang joins the army, arrest Zhang Jin immediately."

Soon Zhang Jin was already trembling and kneeling under the lobby.

Zhang Wei was shocked: "Zhang Jin, do you have anything to say now?"

Zhang Jin looked at Zhang Wei tremblingly: "I, I don't understand, how you, how did you suspect me, how did you know that Luo Ying had something to do with me."

Zhang Wei sighed and said, "Actually, I was suspicious of you from the beginning. I clearly remember that since I took office, you have reported the case several times, and Yujuan was harassed by hooligans, but this Lu Si harassed Yujuan several times, and he was more powerful than any hooligan before, but you didn't report the case, why? There is only one reason, and that is that from that time on, you have been planning to kill Yujuan. That night, you knew that Lu Si was waiting outside the yard, and you should have carefully protected Yujuan at home, but you left, and the reason for leaving was just to help your neighbor install a peachwood knife. ”

"Just when Lu Si thought he had killed Yujuan and was about to escape, you came back, so he sent him to the official mansion. This makes me feel weird, isn't that too much of a coincidence? Imagine, if it were Lu Si or Luo Ying, two strangers, let alone feeding poison to Yujuan, even if she was asked to drink water, she might not be willing to drink it, but if she was forced to pour it, there should be traces on the scene, but there was nothing else except the blood stains on the bed. But if you, the father, bring the medicine to her, then it's different. ”

"I inquired that Yujuan costs a tael of silver every month just for taking medicine, and you gradually can't afford it, so you have a motive to kill. However, at the time, I thought, these may be my inferences, she is your biological daughter after all, how can you kill the killer? However, when I was designing for Luo Ying to surface, I noticed his knife. You made the sword, but you said you had forgotten who it was for. Although it is not against the law of the country for blacksmiths to cast short-edged weapons, they must write down information about when and by whom. But why don't you? So I conclude that your purpose in doing this is to hide your relationship with Luo Ying. When I said that Luo Ying might be the real murderer of Yujuan, you didn't seem to be very interested, but asked me to quickly behead Lu Siwen. Imagine a normal person who doesn't want to know who the real murderer is when his relatives are killed? Unless he has a ghost in his heart! So I am even more convinced that you and Luo Ying not only know each other, but may also have jointly created this case. So I found someone who looked very much like you and begged me to kill Luo Ying. Of course, Luo Ying was about to burst into a rage, so he showed his original form and explained the truth of the matter. ”

Hearing this, Zhang Jin collapsed to the ground.
